To all whom it may concern: n j y Be itknownthat we, WARREN V. JOHN- soN and kROBERT C. KEPNER, residingv at Bloomsburg, Pennsylvania, andfbeing citizens of. the United States, have invented certain new and. useful Improvements in Mine# Car Running-Gear, of which the following is a full, clear, and exact description, such as will enable others skilled in the art t0 which it appertains to ymake and to use the same, reference being hadto the accompanying drawings, which illustrate the lpreferred form ofv the inventionl though it isto be understood that the invention is not limited to the exact ldetailsof construction shown and described, asl it.- isf obvious thatvarious modifications thereof will occur to persons skilled in the art.

This invention relates to new and useful improvements in what are; known as tight and loose running gears, especially adapted for use in mine cars, vand comprises cera'nd arrangement of parts, all as hereinafter fully described and particularly pointed out in the claims. 2 i

, The object ot' the invention is to provide a running gear for `mine cars of maximum strength, in which onel of the wheels of the assembly is secured fast to and rotatable with the axle and thc otherwheel at the opposite end of lsaid axle is held in position by suitable means passing through the axle,

but not through the wheelaso that thewheel may be rotated independently of the axle.

The invention rclatcsto means for connecting the journal-box to the car, means for utilizing substantially all of the lubricant which is injected Aint-'o *the wheelinterior ofV journal-box assem- `connect the pairs lMINE,can RUNNrNG-GEAR Speccation of Letters Patent.

The journal-box is relatively deep andzisA provided at its inner portion, z'. e., the por- `tion nearer the central longitudinal axis ofk the car with an oil cavity' 8, which may be filled with waste orgother suitable oil reretaining packing 11.-
